The worst customer service is reliance. Having reliance datacard and never responded to the queries. It is our fate of having such company

There is no option to give 0 rating otherwise I would have been given that rating. One of the worst in service and didnt know how all governments are accepting the arrogance of this network. I am having wifi and suddenly they disconnected the service and forcing to make payment for 4G for the upgradation and sent mail for the current operation of 3G which I got in just 3 months but no response till date.
